Original application and December 2,191 Serial No. 134,714. Divided and this application filed *June i5;

1917. -"Seria1No. 175,008. I

To all whom it may concern Be it known that I, THADDEUS -S. GR-IMEs,

of Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in vGrinning-Ribs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it'appertainsjto make and use the "same. i

I have found in ginning that lint will accumulate from the underside of the ribs and gather between and around the ribs at the ends of the ginning spaces, that -=is,;where the ribs are attached to the ribrail. This causes a choking in'the ginning'spaees be tween the ribs and retards the eflfective action of the saws. Myobject is to overcome this difficulty.

Figure 1 shows the general design of the rib and Figs. 2 and 8 are detail perspectives showing its attachment to the rail.

.The rib 1 is shown secured at its' lower end to a rail 2, its upper end being supported by a rail 3 which will be understood to be intended for use adjacent a ginning The arrangement and operation of the ribs may be as shown and "described in Letters Patent No. 1,244,196, issued on my application October 23, 1917,0f. which this case 1s a division.

The rail 3 is-forn'led with a strip a at its edge adjacent the saw cylinder, that is, at

the point of engagement of the ribs. s Each rib is formed with a lug 5 -to bear against the front face of the rail and is rabbetedto receive the strip 4; The extremities 6 ofthe ribs are rigidly secured to the rail,

The ribs have recesses 7 extendingtoward their ends 6 from points just. over strip 4, the oppositely disposed recesses-coacting to form widened slots at the meeting edges'of adjacent ribs. At their points ofcontact close contacti j 4 It will be understoodv that the main porthe recessed portions constitute channels permitting of the ready united at the rear of said strip.
